Electrical Characteristics
※1 Measuring frequency inductance at 100 kHz.
※2 ( ) are typical value.
※3 Saturation current: The value of D.C. current when the inductance is over 70% of the initial value.
※4 Temperature rise current: The value of D.C. current when the temperature rise is △t＝40℃.(Ta＝20℃)
